To all whom t may concern: i

Be it known that I, Nens H. LaiisnN, a citizen of the United States, residing at Chicago, in the county of Cook and State of tageous to lubricate the engine piston by in.

troducing atomized oil into the steam supply, thus causing the oil to be'widely distributed and lubricate the entire cylinder witi a mimimum of Oil. vThe object of my invention is to provide an improved device for this purpose, and this object is obtained by a construction illustrated in the accompanying drawing, in which Figure 1 is a perspective view of my apparatus associated with the steam supply pipe leading to the engine cylinder.

Fig. 2 is an enlarged View chiefly in axial F ig. 3 is a sectional elevation on the line 3 3, Fig. 2.

Similar numerals refer to similar parts throughout the several views.

'n'the form selected to illustrate the in- `vention the main steam supply pipe which leads from the water to the engine cylinder is represented by the reference numeral 1.i

This is here shown to be arranged vertically. Leading'out through the side of supply pipe 1 is 'a pipe 2 having a receiving Anozzle 3 formed by an oblique cut and facing up stream with respect t0 the direction of iow of steam in pipe 1. Pipe Q is approximately horizontal and connects with the upper end of the down pipe 3. At its lower end pipe 3 connects [with pipe 4 which is arranged horizontally. and passes 'through the side of pipe 1. It is provided at its inner end with a nozzle 6 which faces down stream as shown in Fig. 2. A series of apertures 8l is formed in the top side of pipe 4 for admitting oil and water in the manner hereinafter described. j

Near the outer end of pipe 4 is a casing 10 vwhich surrounds pipe 4, and connects to av pipe 11 which is of considerably larger diameter than pipe-4. rEhe inner end of pipe 11 screws into the side of the main steam supply pipe 1 and the inner end of pipe 8` j A stuffingl nut 13 screws into the outer end of casing 10 and the result is that the casing and the pipe 11 form a 4jacket around the pipe 4. There is no outlet from this jacket except through apertuies'S in the top side of pipe 4. The casing 10 has an inlet 14 into which leads a pipe 16 which branches out of pipe. 3 at a point somewhat above the top casing. Thus the jacket around the ypipe 4 is kept under the steam pressure equal to that in the down pipe 3 at the point where the pipe 16 joins it. The casing also has an inlet. 18 for lubricating oil, the oil being led to the inlet through a pipe 19 leading from a lubricator 20. The l-ubricator may assume various forms, and I have here represented it only symbolically. It ma j' assume the form of a pressure lubricator, or a force feed lubricator, both of which types are on the market and well known to those skilled in this art. simply to supply oil at a predetermined rate to the'casing 10 under a pressure sufficient to force it to enter said casing.

Operation: It will be understood that when steam is iiowing downward in the main supply pipe l, as indicated by the arrows in Fig. 2, a portion of it will circulate in the pipes 2, 3 and 4, the steam entering the nozzle 3, thence 'flowing outward in pipe 2, downward in pipe 3, and inward in pipe 4, nally emerging from nozzle 6 and passing thence toward the engine cylinder. As the inner end or nozzle of pipe 4 is unobstructed, and as the inlet of branch 16 is located in the duct back some distance from said nozzle, there is a greater pressure at the inlet end of branch 16 than in pipe 4; hence a. portion of the steam in pipe 3 will pass through branch 16 into the jacket surrounding pipe 4, and through the apertures 8 into pipe 4, where it will mingle with thesteam -in pipe 4. As the outer surface of pipe 11 of the jacket is cooler than pipe 4, being more directly exposed to the atmosphere, condensation occurs in the j acket;l and after the device has been in operation some time the jacket will become filled with water and oil until the surface of the liquid reaches the level of the upper ends of the apertures 8, as indicated in F ig. 3. Thereupon the steamV blowing down through apertures 8 will entrain some of the oil and water with it, thus causing them to be atomized and commingled with the steam in pipe 4. It will be noted tha in this, the preferred form,
